 Var. pallida Theob. loc. cit. i, 134 ; fig. 28 h (p. 133) wing. 



This species is subject to great variety both in wing and leg 

 markings (Theob.). In some places (Calcutta and Nagpur) it is 

 common in houses, whereas in others it is said to seldom visit them. 



The larva has been observed by Capt. James and others. In 

 Bombay it is often found in tanks ; in Nagpur and Madras in 

 open tanks, also in grassy or weedy ponds ; in the Punjab in shady, 

 weedy pools. 



Under natural conditions it is non-malarious, but experiment- 

 ally, parasites have been demonstrated to develop in it (James) ; 

 although Theobald (Monog., i, 134) said that up to then '' experi- 

 ments with human malaria (crescent and tertian) " had failed.
